If two people start a public operation, a third person will never join. After playing many operations in the last few days where two people start on the Battle Barge, the AI third marine will never be replaced by someone joining. This has happened in multiple difficulty levels. I find it hard to believe that no one else would be online to jump in. Just today alone I played for six hours with a friend & not once did a third ever join our public lobbies. It seems to also happen if a random sticks around after an operation is over.

Is anyone else having issues with premade groups?
